Chilling knockout from Hassan N'Dam is 'KO of the year contender'

Boxing doesn't get any sweeter or more terrifying than Cameroonian-French veteran Hassan N'Dam N'jikam's stunning knockout of Alfonso Blanco.

The 32-year-old fighter sent Blanco to sleep after just 21 seconds during a fight in Saint Denis, France, over the weekend.

The fight was never meant to create headlines. Instead news of the knockout has gone global and gifted him an unlikely interim WBA middleweight world title.

It was only a few months ago at the Rio 2016 Olympics where N'Dam was beaten by two amateurs.

The footage of the 35-2 (including 21 knockouts) fighter's destruction of Blanco now makes him one of the most feared fighters of his division.

His right hand now demands that respect after it turned off Blanco's lights before he even hit the canvas during their fight. The Venezuelan boxer's head whacked the floor of the ring nose first without his hands moving an inch to try and soften his fall.

Blanco was a complete mess, sprawled out on the deck with his legs appearing to colvulse in an initially scary scene.

Blanco was eventually able to leave the ring on his own two feet after receiving medical treatment immediately after the fight.

The stunning knockout could be a career-changer for N'Dam, who is now firmly in the frame to win a fight against the winner of the Gennady Golovkin-Daniel Jacobs fight at Madison Square Garden on March 18.
